James S. Booth 1979 <p>The purpose of this report is to present the results of geo­technical, textural, and chemical tests performed on samples from the upper Continental Slope, northern Gulf of Mexico.</p><p>The samples were collected by a piston corer up to 12 m (40 ft.} in length with a head weight of 908 kg (one ton}. The inside diameter of the C. A. B. liner was 89 mm (3.5 inches}. Upon retrieval, the cores were cut in 1.5 m sections, examined for evidence of disturbance, then, if in acceptable condition, were sealed and placed in their in situ vertical position in a refrigerated van. Once ashore, the sections were opened, sealed with wax, recapped and stored as before.</p><p>The cores were split lengthwise for analysis. One half of the core was X-rayed and the radiograph was carefully examined as a further check for disturbance. This half was then archived. The other half of the core was used for the laboratory work.</p> application/pdf 10.3133/ofr79579 en U.S Geological Survey Results of Laboratory Tests on Surficial Sediments from the Upper Continental Slope Northern Gulf of Mexico reports
